This paper aims to discuss rising sea levels at the global, regional, and community scale and illustrate the necessity for public comprehension and involvement. It also aims to demonstrate geographic information systems (GIS) as an efficient tool for modeling and disseminating information with the expectation that coastal communities will benefit by joining in a process to integrate this knowledge into broad‐based decision making.

GIS is capable of creating, analyzing, and displaying sea level rise scenarios enabling local officials to address the negative effects of elevated sea levels by allowing them to identify both built and biotic communities that are at risk, assess the situation, and develop mitigation strategies. The paper makes use of a case study of Daytona Beach, Florida, to examine the impacts of storm surge.

A GIS model, produced for south Florida integrating land use and elevation data to illustrate locations that lie below five feet, reveals that heavily populated urban areas in Miami‐Dade County could be inundated during extreme high tide and storm surge events. The GIS also indicates that much of the Florida Keys has elevations below five feet and is at risk of flooding if sea levels rise at projected rates.

The case study of Daytona Beach, Florida, can be replicated at other coastal locations by using GIS to assimilate spatial data and generate meaningful graphic models to be interpreted by those responsible for minimizing the risks from rising sea levels.

The purpose of this paper is to assess the risk due to climate induced disasters in coastal regions. Coastal areas, being economically attractive and ecologically fragile, need altogether different development approaches. The paper also explores the applicability of stakeholder theory for managing coastal regions in a sustainable manner. This paper should help policymakers when making their decisions to maintain coastal regions’ prosperity.

The paper opted for an exploratory study using secondary information available at various levels. This paper presents the case study of the coastal region of Gujarat. It starts by evaluating the present status of the coastal resources and their degradation. It then assesses the risk due to climate induced coastal hazards. It has critically reviewed the policy response towards coastal issues and problems. The applicability of stakeholder approach had been tested for coastal management.

The paper has identified that in an absence of stakeholder approach, the current planning strategies have failed to deal with coastal issues and problems. The coastal region needs a special attention for sustaining its development. An integrated regional framework for coastal development is required which encompasses trade‐off among various sectors. The region needs a long‐term regional land use planning, which can facilitate the disaster resilience and adaptation strategies for local communities. Finally adopting a stakeholder approach is recommended, to improve the ecological productivity and biodiversity of the coastal region.

The research has important policy implications for the state of Gujarat and infers that the stakeholder approach is the most appropriate approach for planning the development of the coastal region.

The paper has direct policy implications for the government of Gujarat and Government of India. Coastal planning needs a systematic approach to have an integrated development. The use of stakeholder approach can solve many issues and problems of coastal conflicts. Such an approach is very important for the protection and sustainable development of the coastal region. This also has colossal relevance for any developing countries preparing coastal region development plans.

The suggestions incorporated in the paper have also looked into the consideration of environmental conservation and protection of rights to livelihood for marginalized groups such as fishing communities.

The use of stakeholder theory for public sector planning is a new approach in a research. The paper has delved into the requirement of stakeholder approach in coastal planning for developing the coastal economy and conserving the coastal environment.

This paper aims to present a hydrodynamic river modelling by incorporating river flow and sea‐level rise interactions.

Predicted sea levels from renowned studies are put to test on flow scenarios of the Sarawak River in the deltaic city of Kuching, Malaysia. Three cases are drawn for investigation, including one extreme flood event, one normal flow with low tide, and another normal flow with spring tide.

The model predicts a worst case that nearly 5‐6 km² of urban land along the Lower Sarawak River would be under water due to the rise.

Such an indication would draw a clearer picture for strategy and mitigation planning.

Generally sea level estimation involves ocean‐atmospheric modelling. However, the paper argues here that a river model is credible for practical hydrological site‐specific analysis to include increase of sea levels.

Residents of South Florida have been living with the effects of climate change in the form of flooding due, in part, to sea level rise, for more than a decade. However, previous research has characterized news coverage of climate change impacts as concerning distant events in terms of time and place. In this study, we look at coverage of climate change at The Miami Herald from 2011-2015, a time period significant in terms of increased temperatures and flooding levels on city streets. Through a content analysis of 167 articles, this study argues that news coverage of climate change in The Miami Herald was largely pragmatic, linked to a news peg, locally focused and presented via opinion pieces rather than news articles. Furthermore, Miami Herald coverage links distant hypotheses of climate change with local realities, invokes a network of editorial responses, and emphasizes local impacts, particularly in more affluent areas. Findings from this study contribute to understanding how news coverage of climate change as a local story may provide a useful model for engaging the public in adapting to and mitigating against the impact of climate change, and creating social acceptance of climate change policy.

The purpose of this paper is to outline the cause of global warming, its trends and consequences as indicated by the International Panel on Climate Change. Sea‐level rise is one consequence of particular concern to Pacific Island states. It also reviews the views of economists about connections between economic growth and global warming.

International efforts, such as through the Kyoto protocol, to reduce greenhouse gas emissions and their atmospheric concentration are discussed and prospects for post‐Kyoto policies are considered. Ways are also examined of addressing the consequences of global warming for the Pacific Island states. How they will be affected and to what extent is discussed, together with their ability to cope with the emerging problem.

The paper finds that whereas the majority of economists did not foresee a conflict between economic growth and global warming, the possibility of such a conflict is now more widely recognized following the Stern Report. It is predicted that a significant reduction in global greenhouse gas emissions is unlikely to be achieved in the foreseeable future owing to conflicting national interest (a prisoners' dilemma problem) and because is will take time to develop new technologies which will reduce greenhouse gas emissions. However, payment for greenhouse gas emissions (for example, via tradable permits) will accelerate desirable technological advance. Both international political action and efforts to develop and use technologies that lower greenhouse gas emissions need to be pursued. Given current and likely increases in greenhouse gas emissions, continuing global warming in this century (and beyond) appears to be inevitable and consequently Pacific Island states will be adversely affected by sea‐level rise and climate change.

The paper emphasizes that Pacific Island states will suffer great hardship from global warming but are ill‐placed geographically, financially and administratively to prevent or adjust to the possible environmental disasters that await them. Nothing may save some from eventual environmental annihilation.

This paper aims to inform the readers an overview of expected impacts of sea level rise (SLR) and climate change on rice crops area, yield and the urgent need to build climate responsive infrastructures to a coastal district, Alappuzha – a high-risk area which is already under mean sea level (MSL). This research carried out to understand the realities and impacts with respect to the exposures of rise in SLR and possible inundation extent of crop land. The extreme precipitation events have caused crop loss and damage, numerous casualties and enormous economic loss in this district during the recent past and project the likely impacts under anticipated climate change.

Global sea levels have already been risen noticeably as a result of climate change, and this trend is anticipated to continue. To reflect on the research objectives, the paper projects a climate change scenario analysis and impact assessment on the major crop grown, i.e. rice, using a crop simulation model, DSSAT 4.7 as the first part of the study. QGIS 3.28 version and Erdas Imagine software were used for land use land cover analysis and to delineate possible inundation in the major land use land cover, especially in agriculture area under SLR scenario. It points out the need to equip the district urgently with climate responsive agriculture strategies as majority of the area comes under 10 mts of elevation as per the Sentinel 2 data. For better adapting to the current and future climate change impacts in the aspects of built environment such as early warnings in farm sector in particular and forests, urban water management, transportation systems, building construction and operation and land use planning in general. Climate change is no longer a policy issue alone; now it is a common man’s nightmare. For a coastal state like Kerala, extreme climate events during 2018 and 2019 and 2021 have posed substantial impacts and damages on the environment and society. The impacts hit the vulnerable communities in multiple ways.

From the analysis, it was revealed that there is an increasing trend in rainfall observed over the past three decades in Alappuzha district. It is projected that day and night time temperatures may increase in Alappuzha by 2.5°C and 2.6°C by 2100, respectively, under RCP 4.5. With unchecked pollution or emission reduction actions, warming may further rise and hence the median projection when SLR reaches 2.4 meters (8 ft) at Alappuzha to Cochin coast is 2130s. The possible inundation analysis shows that around 53.48% of the coastal agriculture land may be likely inundated if SLR is only with mitigation measures such as extreme carbon cuts, SLR rise can be delayed till 2200. Alappuzha is known as the rice bowl of Kerala; however, it is highly exposed to climate vulnerability in terms of its unique environmental geographical settings like coastal wetlands, lagoons and sand beaches. DSSAT simulations shows that Uma rice, a major ruling variety in the region, may have yield reductions of up to 13% in the near century for Alappuzha.

This paper in general explains the projected climate change perspectives for Alappuzha, a climate change hotspot of Kerala with respect to SLR and coastal agriculture. and a review of the progression of DRR in the built environment and mainstreaming CCA and DRR by government and other agencies in the state.

This study underscores the urgent need for climate-responsive agricultural strategies in Alappuzha, Kerala, due to anticipated sea level rise, climate change, and land use changes. Equipping farmers with the knowledge and tools to adapt is essential for ensuring food security and sustainable livelihoods. Implementing climate-resilient practices and technologies will help mitigate adverse effects on rice crops, promoting economic stability and resilience in the region. Involving local stakeholders in the adaptation process is crucial, as their participation can enhance collaboration, increase awareness, and accelerate the adoption of sustainable agricultural practices, making the transition smoother and more effective.

It is the responsibility of the scientific community to inform the knowledge gained for the benefit of the society, especially on criticality of altering the existing land use pattern and building climate resilient coastal infrastructures. Studies such as this can stand as basis for implementing planned adaption actions. This is to conclude that instead of working in silos, mainstreaming climate change adaptation holistically across sectors is very necessary at this crucial hour. Participatory action plans and policies involving all local stakeholders can strengthen awareness and fasten the learning processes for adaptation including managed retreats.

At present, there are no specific studies, on the impacts of climate change and SLR on rice cropping systems in the district which specifically inform how to mainstream adaptation in the agriculture strategies in low lying coastal zones of Alappuzha.

This study aims to support the development risk management strategies towards improving the resilience of assets located in the estuary and lower level of the Swan River, Western Australia. The study evaluated the key role of Federal/State policies in adaptation planning and the communication and interface between various stakeholders, including State/Local governments, construction professionals, property developers and landowners.

The study applied a mixed research approach through a questionnaire survey followed by an in-depth interview involving local construction experts. Collected data were analysed following the grounded theory methodology style of data analysis.

The findings revealed a convoluted understanding of communication networks and responsibility for owning the future risks between relevant stakeholders. As a result, a framework illustrating clear process and roles in mitigating risk and implementing adaptive asset management measures has been formulated and presented in this study.

Scientific evidence suggested that sea-level rise and increased frequency of major coastal flooding events are inevitable as early as 2100, and having a comprehensive risk management plan of assets to anticipate climate risks and to improve urban resilience is essential. The proposed framework is aimed at local stakeholders in improving current state of communication and adaptation planning as a pathway to develop a robust risk management strategy.

In 2001, the Intergovernmental Panel on Climate Change's Third Assessment Report revealed an important increase in the level of consensus concerning the reality of human-caused climate warming. The scientific basis for global warming has thus been sufficiently established to enable meaningful planning of appropriate policy responses to address global warming. As a result, the world's policy makers, governments, industries, energy producers/planners, and individuals from many other walks of life have increased their attention toward finding acceptable solutions to the challenge of global warming. This laudable increase in worldwide attention to this global-scale challenge has not, however, led to a heightened optimism that the required substantial reductions in carbon dioxide (CO2) emissions deemed necessary to stabilize the global climate can be achieved anytime soon. This fact is due in large part to several fundamental aspects of the climate system that interact to ensure that climate change is a phenomenon that will emerge over extensive timescales.

Although most of the warming observed during the 20th century is attributed to increased greenhouse gas concentrations, because of the high heat capacity of the world's oceans, further warming will lag added greenhouse gas concentrations by decades to centuries. Thus, today's enhanced atmospheric CO2 concentrations have already “wired in” a certain amount of future warming in the climate system, independent of human actions. Furthermore, as atmospheric CO2 concentrations increase, the world's natural CO2 “sinks” will begin to saturate, diminishing their ability to remove CO2 from the atmosphere. Future warming will also eventually cause melting of the Greenland and Antarctic ice sheets, which will contribute substantially to sea level rise, but only over hundreds to thousands of years. As a result, current generations have, in effect, decided to make future generations pay most of the direct and indirect costs of this major global problem. The longer the delay in reducing CO2 and other greenhouse gas emissions, the greater the burden of climate change will be for future life on earth.

Collectively, these phenomena comprise a “global warming dilemma.” On the one hand, the current level of global warming to date appears to be comparatively benign, about 0.6°C. This seemingly small warming to date has thus hardly been sufficient to spur the world to pursue aggressive CO2 emissions reduction policies. On the other hand, the decision to delay global emissions reductions in the absence of a current crisis is essentially a commitment to accept large levels of climate warming and sea level rise for many centuries. This dilemma is a difficult obstacle for policy makers to overcome, although better education of policy makers regarding the long-term consequences of climate change may assist in policy development.

The policy challenge is further exacerbated by factors that lie outside the realm of science. There are a host of values conflicts that conspire to prevent meaningful preventative actions on the global scale. These values conflicts are deeply rooted in our very globally diverse lifestyles and our national, cultural, religious, political, economic, environmental, and personal belief systems. This vast diversity of values and priorities inevitably leads to equally diverse opinions on who or what should pay for preventing or experiencing climate change, how much they should pay, when, and in what form. Ultimately, the challenge to all is to determine the extent to which we will be able to contribute to limiting the magnitude of this problem so as to preserve the quality of life for many future generations of life on earth.

The purpose of this paper is to present an overview of the vulnerability of Florida’s coastal destinations to climate change and the costs of the adaptation measures required to cope with the impacts of climate change in a range of current and future scenarios.

The paper illustrates a range of current and projected climate change scenarios in Florida, the challenges the state is already experiencing in dealing with the impacts of climate change and some of the measures adopted to date in three particularly vulnerable coastal destinations, namely Fort Lauderdale, Miami Beach and Sarasota.

Although tourism is the number one industry in Florida, the state holds a particularly vulnerable position with respect to climate change. The vacuum of political will to address these issues at the state level is thus of particular concern given the vulnerable position of Florida’s coastal areas. With nearly 10 percent of its land area lying at less than one meter above the present sea level, adaptation is especially urgent in Florida. The local government of Florida’s cities such as Fort Lauderdale, Miami Beach and Sarasota are not willing to surrender to sea level rise (SLR). However, without a strong political will to address climate change at the state and federal levels, the costs of adapting to an escalating SLR are becoming progressively unsustainable.

This illustrative case study paper provides a contemporary synthesis of the implications for Florida’s coastal tourism destinations of rising sea levels and those adaptation strategies deemed appropriate in the search for their longer-term sustainability.
